When I checked "FreeBSD-4.8's Hardware Compatibility Lit", I didn't see any "CNet PRO200" but I saw a "CNet/PRO" which I suppose are just the same. So, I recompiled my Kernel again just in case FreeBSD didn't recognize this newly installed Cnet LAN card. But, nothing changed after Kernel recompilation. (But I did not change any option in the Generic kernel; just re-compiled it).

The output of dmesg and ifconfig would be helpful in diagnosing this. I suppose
that's major PITA though considering you're LAN isn't working. At the very least,
the first entry that comes up with ifconfig would be very helpful.
